Covers multiple ML domains including customer churn prediction, topic modeling with both scikit-learn and Apache Spark, and collaborative filtering recommender systems using KNN, ALS, and neural networks in Keras. Demonstrates distributed computing approaches for large-scale analysis, contrasting single-machine workflows with Spark's fault-tolerant cluster computing for processing at scale. Includes hands-on NLP implementations across NLTK, spaCy, and Gensim libraries, with notebooks designed for portability across Jupyter, Databricks, and Google Colab environments.
